.To all 'whom't concern.'

l Be it known that I, HENRY KJSTONER., of Lancaster, `inl Vthe county` of Lancasterv and State ofl Pennsylvania, have invented a new audhnproved Device for Holding and Secur- 'ing the'Iron Teeth used on Horse-Rakes; and

'I do hereby-declare that the following is a' full, clear, and exactl description thereof, reference being had to the accompan yin g drawings, mak- 'finga part of this specification, in which'- Figure 1 is a perspective view of the device or tooth-head lwith'a. spiral spring attached thereto, the screw-bolt and burr G H detached. Figf2 shows the same with' the tooth, &c., in place; also, the eye I of the tooth,'

through which` the bolt enters tofasten the tooth ou B and prevent its vertical action,

lcon'tlned in the notch f, resting n the beveled base o of the head A, Vshown one-third full size,

clearly illustrating its construction and applif cation.

Any number of [the tooth -heads' are employed-oue for each tooth-. side by lside on a rod, M, passing through the perforated ears D D. The teeth L-are laid in the notch f on rc, andbolted on the raised head B, so that each tooth may be raised independently on its head, or collectively, as the case may be. By contuing' the-teeth in a notch the'elasticity of A eri'its' projecting toethsupport c' the necessity of loosening' the vspringwill be avoided. In the case where keys are employed to hold the springs they must first be removed before the tooth canbe replaced, which'is-always troublesome.

The device for holding the tooth irmlyin its place on the bolt to prevent its vibration, coniined as shown, the oscillating or vibrating tooth.heads, -with the'springs directly at; tached to 'themfins'teadiof being attachedto keys, makes this -a highly-desirable improvement on horse-relies; and although I am aware that various kinds ofitooth-heads and springs are employed, I am not aware ot any that are substantially the same. 'And the advantages obtained by' this simple device is believedV to be as novel' as-it isuseful in the construction and application of the'teeth vand springs to. the same.

What I claim as my invention, and desire 'to secure by Letters Patent, is,-

1. lhe construction and application 'of the tooth-head A, withits perforated ears D D raised, and notched flange B fyfor holdingand securing the teeth, inthe manuel"specified.

2."] he.supportxng and projecting base c. in combination with the projecting iiange, with Aits notch, for the additional purpose ofattaching the springs, inthe manner speced.
